provements in Horseshoes, of which the following is a specification.

This invention relates to a construction of horse shoe devised with theobject of diminishing concussion to the animal, which consists inconstructing the heel portion of the shoe in a manner as hereinaftermore specilically referred to, whereby all the advantages of elasticityol tread and the consequent avoidance'of concussion due to hardpavements or roads are obtained, without, on one hand, the disadvantageas regard want of durability for the shoe7 and on the other hand7injurious effect upon the animals hooi, and to this end the inventionaims to provide the shoe with a pair of removable cushioned calks set upin a manneras h ereinafter set forth, so as to prevent the animalaccidentally pulling olf the calk in case of meeting with anobstruction.

' The invention further aims to provide the shoe with a removable andreplaceable calk provided with a removable and'compressible cushioningmeans and which r can be readily fitted to horseshocs now in general useWithout the necessity of any special machinery or tools, and withoutchanging the contour of the shoe whatso` over; and to furthermoreprovide means whereby the compressing of the .cushioning element will belimited7 thereby securing longevity of the latter, said means alsoconstituting a stop to limit the'moveinent in one 'direction of thecall; proper.

. The invention further aims to provide a removable and replaceablecushioned calkl for horseshoes which shall be simple in itsconstruction, strong, durable,

' elicient in its use, readily applied to the heel portion of the shoe,and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists inthe novel construction, combination and arrangement of parte hereinaftermore specifically described and illustrated in the' accompanyingdrawings, wherein is shown the preferred embodiment o th e invention,but it is to be understood that changes,

variations' and modifications can be resorted to which comewith in thescope oi' the claims hereunto appended.

In the drawings wherein 'like reference characters l denotecorresponding parts throughout the several viewsli`igure 1 is aperspective view the heel portion ol a horseshoe. Fig. 2 is alike viewoi a removable calla. Fig. 3 is a longitudinal sectional view of theparts shown in Figs. 1 and Zwhen assembled. Figs. 4;

. and 5 are views similar to Figs. 1 and 2.

Fig. 6 is` a View similar to Figs. 1 and 2. Fig. 7 isa view similar toFig. 3 when the parte shown in Fig. 6 are assembled.

Referring to the drawings by reference characters 8 denotes the heelportion ofthe shoe having on its lower lace near the outer end thereof aheaded stud v9, further providedwith arecessglO in the said lower faceand also having an opening 11 to receive a holdg fast devicel to behereinafter referred to.v

12 denotes a calk carrying plate which is offset as at 13, and hasaflattened portion -14 which-is detachable or otherwise connected totheheel portion 8 by means of the hold-fast device 15 which passes throughthe opening ll and `a suitable opening in the portion 14 of the calkcarrying plater Thel calk is indicated' si by the' reference character16.. Secured to theinner face of the portion 14 is a holding plate 17having a. keyhole-shaped opening 1S. Interposed between the plate 17 andthe plate 12 is a cushion element 19. The cushi'on element 19 isretained between the-two plates l2 and 17 through the medium of a headedpin 20 which is secured at one end ofthe calk 16 and extends through theplate l2, the element 19, the plate 17 and is head-ed asat 21,thesaid'headedcnd 21 of the pin 20 playing Ain the recess 10 for-mediathe heel portion of the shoe; The pin 20 not only acts asa means forretaining the cushion element 19 in position, butalso acts as a stop forlimitingthe movement in eitherdirection of the offset portion of thecalk carrying plate 12. This will be evidentffor the reason that themove- -ment in one direction is arrested when the head 21 engages thewall of the recess 10, and movement in* the other direction is arrestedwhen the head 21 engages the` plate 17. The headed stud 9 is shoulderedas at` 22 so as to-prevent said stud being'or'c'ed through the heelportion of the shoe and injuring theanimals hooi, and the headed stud 9is adapted to engage in the keyhole-shaped opening 18 in a manner asshown in Fig. 3, yso that the offset portion'ofithe calk carrying plate12 with the cushion element 19 and the plate 17 will be detachablyconnected to the heel portion 8 of the shoe. The keyhole-shaped opening1S and the pin 9 constitute a pin andslot connection between ithc'cushion calk and the shoe, and also act as a means to prevent thecushioned calk from being accidentally .pulled oft' the shoe when theanimals hoof meets with an obstruction. V

The construction shown in Figs. 4 and 5 is the same as that shown inFigs. 1, 2 and 3 with the exception that the opening 23 in the plate 17is oa differentcontour, that is to say, it is substantially T T-shapedwith one end wall and is arranged at the outer end oi .the plate'17otherwise than-that stated in connection reference characters beingapplied thereto.

In connection with the construction shown in Figs. 6 and 7 the head 21of the pin 2() is seated in a countersunk opening 24 in the plate 17.The headed stud carried by the heel portion of the shoe inV Fig. 6 hasthe head thereof oblong as at 25 in lieu of circular as shown' inFig. 1. Theopening in the plate 17, indicated by the reference character26, corresponds in contour to the shape o .the head 25 of the pin 27,but the opening 26 extends at a different angle with respect to thedirection in which'the head 25 of the pin 27 extends so that itisnecessary t0 give the cushion calk e almost a half turniin moving it tooperative position With respect tothe heel portion oi the shoe. The heelportion of the shoe, as shownin Fig. `6, is provided with a circularrecess 28l to receive the head 21 of the pin 20; otherwise than thatstated the construction lshown in Figs. 6 and 7 is the same, as shown inthe other gures of the drawings, the same reference characters beingapplied thereto. v

It will be evident` from the foregoing construction of horseshoes that asimple and inexpensive cushion calk is sei; up which can be'readilyfitted to the shoe, and furthermore, means are set up to' prevent theacciv dental pulling ofi of thecalk plate by the animal.

It will furthermore be evident that no special shoe construction isnecessary, which is a material advantage, or the reason that it permitsthecalk to be fitted to any style of shoe n'ow in general use. l

It will furthermore be evident that the elasticity -of the treadobtained by the construction ofthe shoe in the manner set forth has theeffect not only in diminishing concussion, but of increasing thedurability of the shoe, and furthermore, the cushion element besidesaffording elasticity of tread, acts als?) as insulators to prevent thetransmission tothe hoof of the heat generated by irictiona'l contactwith the hot pavement.'

What We claim is- 1. A calk carrying plate having an offset portion, aholding plate secured to one end of the calk carrying plate, a cushionelement interposed between the plates, means for retaining the cushionelement between the plates,

means for connecting'one end of the calk carrying and holding plates totheheel portion of a horseshoe, and a pin and elongated slot connectionbetween thel other end of said holding plate and horseshoe.

2. The combination of a holding plate, a calk carrying plate having theforward end connected to said holding plate and further having an offsetportion extending from said holding plate, means for connecting theforward ends of the said plates to a horseshoe, a cushion elementinterposed between said plates, and a pin and elongated slot connect-ionfor detachably connecting said holding plate to the heel portion of ahorseshoe.

3. A removable cushion calk comprising a'holding plate, a pin andelongated slot connection between the holding plate anda horseshoe, acalk carrying plate having one end secured to said holding plate and aportion thereof offset from the said holdingplate, a cushion elementinterposed between said offset portionvand the holding plate, and meansfor securing said cushion element between said plates and for limitingtheme/vement in either direction of said offset portion.

4; A calk carrying plate having one portion thereof attnched Ito ahorseshoe and itsy other portion offset, a cushioning elementinterposed-between the offset portion and the shoe, a headed pin, andmeans adapted to be slipped r er the inner face of the head of the pinfor detachably connectingthe offset portion of the plate to a horseshoe.

In testimony whereof we have hereunto set our hands in presenceof twosubscribing witnesses.
